How to Mine Grin (GRIN): Complete GPU Mining Guide 2026

Grin is a minimal MimbleWimble coin with linear emission (60 GRIN per minute), GPU-mined with Cuckatoo32. This guide shows step by step how to mine Grin on VeinPool, a French mining pool with a 1% fee and no sign-up: your wallet address is all you need.

Grin at a glance

Ports

• Pool (PPLNS): stratum+tcp://veinpool.fr:3380 · TLS: stratum+ssl://veinpool.fr:13380
• SOLO: stratum+tcp://veinpool.fr:3382 · TLS: stratum+ssl://veinpool.fr:13382

1. Get a GRIN address

You need a GRIN receiving address whose keys you control: the official Grin wallet is the safest choice. Avoid exchange deposit addresses for solo mining: some exchanges do not accept block rewards (coinbase).

2. Download a mining software

Miners that work with Grin on VeinPool. Only download them from their official page (links below); the fees shown are the software's own dev fee, separate from the pool fee:

• lolMiner — NVIDIA · AMD · recommended · version 1.98a · dev fee 1%
  Windows Linux official page

3. Start mining

Replace YOUR_ADDRESS with your GRIN address and rig1 with your machine's name. Command for each miner (port 3380):

lolMiner

lolMiner.exe --algo C32 --pool veinpool.fr:3380 --user YOUR_ADDRESS.rig1

On Windows, paste the line into a .bat file inside the miner's folder; on Linux, start the program with ./ followed by its name. On the Grin page above, the generator writes the full command (PowerShell, .bat, Linux, HiveOS, MMPOS) with your address and a Copy button.

Pool (PPLNS) or SOLO?

PPLNS pool: everyone's hashrate is combined and each block is split according to the work each miner really did. Steady income, recommended for most rigs.

SOLO: your rig mines alone; when it finds a block it receives the reward (60 GRIN) minus the 1% pool fee. On a small network like Grin, a single machine can find blocks regularly; the calculator shows your exact odds.

How much can you earn mining Grin?

Earnings depend on your hashrate, the network difficulty and the GRIN price. The Grin calculator estimates them live (pool and solo); electricity cost is optional. The hardware ranking compares GPUs and CPUs.

Common problems

• Antivirus deletes the miner: most antivirus software flags mining tools. Only download them from their official page (links above), then add an exclusion for their folder.
• No stats on VeinPool: check the address, port and hostname; stats appear after the first shares (1 to 2 minutes).
• Hashrate lower than expected (GPU): update your graphics driver and close apps that use the GPU (games, browsers playing video).
